## OpenMP 4.0 about to be released and IWOMP 2013
So much has been happening in OpenMP since SC 12 that I hope to capture it all in this post while flying to the ADC C++ meeting where I will talk about C++14, ISOCPP.org, and Transactional Memory. First, the research arm of OpenMP is IWOMP, the annual research conference. You probably know by now that IWOMP 2013 will be in Canberra, Australia instead of its usual June summer time frame. This means that there is time (up till May 10) for new proposal submission. So if you have some research in OpenMP that should be exposed, please submit a... [More]

## MASS v6.0 -- High performance math libraries for POWER7
Mathematical Acceleration Subsystem (MASS) Version 6.0 for AIX has been released. This high performance suite of elementary and special mathematical functions contains two new libraries tuned for the IBM POWER7 processor, and exploiting the POWER7 VSX SIMD instruction set. MASS v6.0 offers performance on POWER7 of up to 260 times that of the system math library libm, and up to 4 times that of previous versions of MASS. MASS v6.0 ships with the IBM XL C/C++ for AIX v11.1 and XL Fortran for AIX v13.1 compilers, which provide for both explicit... [More]

## MASS auto-vectorization paper now on developerWorks
If your applications call mathematical functions such as sin, cos, exp, log, etc. and you are interested in maximizing performance with minimum effort, here is something that will interest you! My colleague Daniel Zabawa and I have written a paper, "How to improve the performance of programs calling mathematical functions -- taking advantage of IBM XL C/C++ or XL Fortran compiler auto-vectorization". Our paper introduces the IBM MASS high-performance mathematical libraries, and demonstrates how to benefit from them — without the need for... [More]

## MASS high-performance mathematical function libraries
Hello -- I'm the technical leader for the IBM MASS math libraries. MASS stands for Mathematical Acceleration Subsystem, and consists of libraries of mathematical functions specifically tuned for optimum performance on various computing platforms. MASS was originally launched by IBM in 1995, and has been continuously improved and expanded since then. I've been involved with MASS since 2002. There are currently versions of MASS for all the POWER processors, running AIX or Linux operating systems. There are also versions for BlueGene/L and... [More]
